SAFETY APPLIANCE FOR ELEVATORS,

Application filed May 4, 1923.

To all whom it may concern:

Be it known that I, EDMOND TURGEON, a citizen of th United States of America, and a resident of Thompsonville, in the county of Hartford and State of Connecticut, have invented a new and useful Safety Appliance for Elevators, of which the following is a specification.

My invention relates to improvements in safety appliances for elevators, and consists essentially of elevator and landing trip mechanisms, means operated by the elevator in ascending and descending, when and accordingly as said elevator-trip mechanism, or said landing-trip mechanism is released, to throw off or disconnect the power from said elevator, and setting or resetting means, all of peculiar construction and arrangement, and combined in a new and novel' manner,'together with such subsidiary and auxiliary parts and members as may be necessary or desirable in order to render the appliance complete in every respect, all as hereinafter set forth.

This invention is in the nature of an improvement of the safety appliance for elevators covered by Letters Patent of the United States, No. 1,314,228, issued to me August 26, 1919, and has similar objects in view, namely: to provide means automatically to out off the power from an elevator, whether the latter be ascending or descending, whenever an animate or inanimate obstacle or obstruction is thrust beyond the landing or floor into the path of the descending elevator, or is in the bottom of said well and so in such path, on the one hand, beyond the elevator floor into the ele vator well when the elevator is ascending, on the other hand; to provide such means which is applicable to practically any type of elevator, power, and power-controlling mechanism; to produce an appliance of this character which prevents the elevator from being started without first setting or resetting whichever trip mechanism has been sprung, or both trip mechanisms, if both were sprung, and from being restarted when stopped by an obstruction, until such obstruction is removed; and to afford protection to the obstruction from the appliance itself.

Still another object is to cause the elevator to be brought to a stop as it approaches a landing from above or below, in the event the landing-trip mechanism be operated Serial No. 636,596.

while the elevator is at a considerable distance from said landing.

The appliance is adaptable to elevators of any size and regardless of the location and number of entrances thereto, and to any number of floors, to engineand electricmotor-driven and hydraulic elevators; and to ropeor cable-controlled and electric-controlled elevators. i

Other objects and advantages will appear in the course of the following description.

A preferred embodiment of the invention, whereby I attain the objects and secure the advantages of the same, is illustrated in the accompanying drawings, and I will proceed to describe said invention with reference to said drawings, although it is to be understood that the form, construction, arrangement, etc., of the parts and members in various aspects are not material and may be varied and modified without departure from the spirit of said invention.

In the drawings, in which like reference characters designate like parts throughout the several views, Figure 1 is a front elevation of an elevator well and elevator, showing applied to the latter a practical embodiment of my safety appliance as aforesaid, a landing or floor appearing in section, and a portion of the top of said well and a ortion of said well below said floor being roken out; Fig. 2, an inside elevation of the lefthand side or wall of the well, and of the members on that side, the top of the well and a fragment of said floor being in section, and a portion of said well below the floor being broken out, as in the first view and also in the next view; Fig. 3, a similar view looking toward the right-hand wall of the well; Fig. 4, an enlarged detail taken on lines H, looking in the direction of'the associated arrow, in Fig. 10; Fig. 5, a top plan of the well and mechanism mounted thereon; Fig. 6, an enlarged detail taken on lines 66, looking in the direction of the associated arrow, in Fig. 10; Fig. 7, a side elevation of one of the electric-switch-operating members; Fig. 8, a side elevation of another of the electric-switch-operating members; Fig. 9, a top plan of the belt shipper; Fig. 10, a bottom plan of the elevator and mechanism carried thereby, one of the corner brackets being in section; Fig. 11, an enlarged, cross section through the shoe; Fig. 12, an enlarged, vertical section through the elevator taken from back to front and looking toward the right; Fig. 13, an enlarged, front elevation of said shoe and associated parts and members, including the setting or resetting mechanism or device; Fig. 14, an enlarged, right-hand side elevation of the' elevator and mechanism carried thereby; Fig. 15, an enlarged, front elevation of the landing-trip mechanism, and, Fig. 16, an enlarged, left-hand side elevation of said last-named mechanism.

In illustrating the application of my invention, I have deemed it necessary to show merely rightand left-hand, side Walls 1 and 2, respectively, a rear wall 3, and a top 5 of an elevator well, without any of the customary enclosing members, includin gates or doors, at the front, a single landing or floor 7 in front of said well, and a very simple form of elevator. It is to be understood, however, that, in practice. exposed and unprotected spaces in front of the well will be closed, there may be any number of floors or landings, and the elevator may be as elaborate in structure and furnishings as desired. I have, furthermore, shown the elevator raised to an unusual height in the first view, but this is done in order to expose more of the appliance in said view, and a clear understanding of the operation is not thereby interfered with.

Although the entrance to and exit from the elevator, in the present example, are presumed to be at the front and there only, the appliance is equally well adapted for and adaptable to an elevator which opens on any other one side, or on any two or even more sides, it only being necessary to arrange, locate, or extend the yielding guards accordingly. And there may be any number of floors, each equipped with the landingtrip mechanism.

The walls .1 and 2 are provided inside with vertical elevator guards 8-8.

The elevator, which is designed to travel up and down between the guides 8, consists of a floor or platform 9, and two uprights 10 at the sides, which uprights are connected at the top by a cross-bar or beam 11.

Carried by brackets 1212, which are secured to the under side of the platform 9. are two pairs of anti-friction rolls 13, said. rolls being located by said brackets beyond the rightand left-hand edges of said platform in position to engage the guides 6 for the purpose of holding the elevator in place as it moves up and down. One roll 13 in each pair is in front of the contiguous guide 8, and the other roll 13 is behind such guide. There are similar brackets 12 secured to the end portions of the beam 11 and equipped with rolls 13 to engage the guides 8.

In the center of the top of the beam 11 is an eye-bolt 14, and a chain or cable 15 is attached at one end to the same. The cable 15 passes upwardly, from the eye-bolt 14, through an opening 16 in the top 5 and between a pair of sheaves 17 mounted on spindles which are journaled in said open ings, to a drum 18. The drum 18 is secured on a horizontal shaft 19 which is journaled in two bearing brackets 20 mounted on and secured to the top 5. The shaft 19 is parallel with the cross-bar 11. Secured t the shaft 19 at the right of the drum 18 is a worm-wheel 21. Journaled in front and rear bearings 22 and 23, respectively, which hearings are also mounted on and secured to the top is a shaft 24. The shaft 24 extends beneath the worm-wheel 21 at right-angles to the shaft 19, and there is a worm (represented by dotted lines at 25 in Fig. 1) secured. to said first-named shaft with which said worm-wheel intermeshes. The shaf 24 also extends beyond the back edge of the top 5, and mounted loosely on the overhanging portion of said shaft are two pulleys 26, and secured to said shaft between said pulleys is a pulley 27. The pulleys 26 and 27 are driven by two belts 28. The forward belt 28 is adapted to run on either the forward pulley 26 or the pulley 27, and the rear belt 28 is adapted to run on either the rear pulley 26 or said pulley 27. The rear belt 28 is crossed or otherwise adapted to drive the pulley 27 in the opposite direction from that in which said pulley is driven by the front belt 28. These belts themselves are driven from a pulley on the shaft of an electric motor (not shown), or other engine or motor.

A shipper is provided for the belts 28, each shipper consisting of a rod 29 having two pairs of fingers 30, a. rock-shaft 31 hav ing an arm 32 with its upper end pivotally connected at 33 with the forward end of said rod. and actuating means subsequently to be described for said rock-shaft. An. angular. bearing bracket 34 is attached to the back wall 3 of the elevator well in position to afford a journal for the rear terminal of the shaft 24, and a support for the rear terminal of the shipper rod 29--see Figs. 5 and 9. The rod 29 extends rearwardly, from the rocker arm 32, through an opening 35 in the wall 3 to and through an opening in an upstanding arm 34 at the rear end of the bracket 34, such lastnamed opening being below an opening provided in such arm for the reception of the shaft 24. The fingers 30 in the front pair are on the right-hand side of the rod 29 and in position to receive between them the front belt 28, and the fingers 30 in the rear pair are on the left-hand side of said rod and in position to receive between them the back belt 28.

Mounted on and secured to the top 5 are two pairs of bearing brackets 36 and 37 the latter being at the left of the former, and all being in front of the other mechathe lower block when said meas es nism on said top. The upstanding portions of the brackets 36 inclined toward each other, and each of'such portions carries a stud 38 upon which is loosely mounted a sheave 39. A sheave 40 is loosely mounted on a stud 4C1 carried by the brackets 34". The vertical plane in which the groove in the sheave 40 is located if continued to the right, would pass between the sheaves 39. A cord or cable 42 passes over the sheave 40 and has two branches 43 which pass over the sheaves 39. There are two counterweights id on the branches 43 of the cable 42 at the left of the sheaves 39.

The rock-shaft 31 is journaled in two hangers :5 which depend from the top 5, and secured to said rock-shaft at the lefthand terminal is a sheave as. A power-controlling or starting and stopping rope or cable 47 passes over the sheave 46, and under asheave 72 which is loosely mounted on a stud 48 that projects inwardly from the wall 2, the ends of said cable being secured to said last-named sheave. Adiustably secured to the back reach of the cable 4'? are upper and under stop blocks d9-l9. A perforated lug 50 is secured to the top and projects beyond the left-hand edge of the platform 9 in position to receive the back reach of the cable 457. The part of the lug 50 through which the back reach of the cable 4-7 extends is between the stop blocks 49, and the latter are so located on said reach that said lug encounters the upper block when the elevator approaches the extreme limit of its upward travel, and encounters elevator ap proaches the lower limit of its downwart travel, with the result that said reach ac cordingly is actuated upwardly or downwardly. The contact between the cable l7 and the lug 50 otherwise is not of a binding nature. The cable l? is, within convenient reach of an operator on the platform 9.

When the rear reach of the cable 47 is drawn downwardly, or the front reach is drawn upwardly, the roclr-shaft 31 is operated, through the medium of the sheave 46, to actuate rearwardly the shipper rod 29, by means of the arm 32, and cause the front belt 28 to be shifted from the front pulley 26 onto the pulley 27, with the re sult that the drum 18 is rotated in the di-- rection to wind up the cable 15, through the medium of the shaft 24;, worm 25, wormwheel 21, and shaft 19, and raise the elevator. And, when the front reach of the cable 4:7 is drawn downwardly, or the rear reach upwardly, the rear belt 28 is shifted from the rear pulley 26 onto the pulley 2'7, through the same intervening parts and members as before, the rod 29 this time being drawn forward by the rocker arm 82, and the drum l8 rotated in the direction to pay out the cable 15 so that the elevator can descend. In each of these cases it is as suined that the cable 4:? is actuated from initial or neutral position. From the above it is clear in what manner the elevator is stopped at either end of its travel by means of the lug 50 and the stop blocked-9.

On the inner face of the wall 2 below the sheave 46 are two lugs 51, and a vertical rod 52 is slidingly arranged in said lugs, said rod having at its bottom end a perforated cross-head 53 through which pass the front and back reaches of the cable 47. Etop blocks 54, similar to the stop blocks 49, are adjustably secured to the front and back reaches of the cable l? above the cross head 53, and, when said cable is disposed with both of said first-named blocks in approximately the same horizontal plane, they then usually being in contact with said crosshead, said cable is in the initial position to which reference was made in the preceding paragraph, that is to say, said cable is initially disposed. That portion of my appliance, which automatically shifts the cable 47 to initial position, equalizing the blocks 5% by causing them to be moved into a common horizontal plane, is termed an equalizer. This equalizer comprises the rod 52 with its cross-head, and the cable 42 with its branches.

The cables 12, after passing over the sheave l0, extends downwardly at the right of said sheave, through an opening 55 in the top 5, into the well to be attached to the upper end of the rod 52. The branches 43 of the cable 42, after passing over the sheaves 39, extend downwardly at the right of said sheaves, through openings 5656 in the top 5, and in front of and behind a sheave 57 in the well, to which sheave said branches are securely attached. The sheave 5'? is secured to a shaft 58 that is journaled in the wall 1 and a hanger 59 depending from the top 5, at right-angles to the vertical plane in which the axes of the studs 38 are located. Secured on the shaft 58 between the wall 1 and the sheave 57 is a sheave 60, and loosely mounted on a stud 61, which projects inwardly from said wall, at the bottom of the same and directly below said shaft, is a sheave 62. An actuator or safety chain'or cable 63 passes over and under the sheaves 57 and 62, respectively, and is secured to said firstnamed sheave. There is sullicient slack in the equalizer cable 42 and its branches 48, when the power-controlling cable 47 is in neutral position, to enable said p0wercontrolling cable to be shifted for starting and stopping the elevator, but each shift of said last-named cable which is made to start the elevator either up or down takes the slack out of said equalizer cable and branches, with the result that there is an approximately taut connection between the sheave 57 and the power-controlling cable, but such connection becomes slack as soon as the power-controlling cable is actuated to stop the elevator.

The cable d7, when actuated out of neutral position, causes the cross-head 53 and the rod 52 to be drawn downwardly, through the medium of whichever block 54 is secured to the reach of said cable that moves downwardly. The downward move ment of the rod 52 takes the slack out of the cable and its branches d3, and the connection between the sheave 57 and the cable 47 is approximately taut. It follows, therefore, that, if the cable 63 be actuated so that the front reach thereof moves downwardly, the sheave is partially rotated and imparts partial rotation, through the medium of the shaft 58, to the sheave 57 in the direction to draw the front branch l3 downwardly and to the right, the rear branch 4-3 being slackened by the operation. The front branch 43 in thus moving to the right carries with it the cable 4:2, and causes the rod 52 with its cross-head 53 to be elevated. In moving upwardly the cross-head 53 carries with it whichever of the blocks 54 is in contact therewith, and so shifts the cable 47 into neutral position and causes the elevator to be stopped. Similar results follow the actuation ofthe cable 63 in the direction to cause the back reach of said cable to descend. In this case the sheaves 60 and 57 are partially rotated in the direction opposite to that in which they were partially rotated in the first case, and the back reach 4C3 is responsible for the upward movement imparted to the rod 52 whereby the cable 47 is shifted to stop the elevator.

Under ordinary conditions or circumstances the equalizer does not affect the cable 17, owing to the presence initially of the slack in the equalizer cable and branches but in the event the cable 63 be shifted from neutral position, (which position is that wherein the sheave 60 causes the sheave 57 to be positioned in such a manner that the distances between the point or points of attachment of the branches 43, to said sheave 57. and the junction of said branches with the cable 42 are equal), the equalizer is caused at once to operate said cable l7 in such a manner as to stop the elevator, whether the latter be ascending or descending. As soon as the cable 63 is returned to neutral or initial position, or is permitted to be so returned, the equalizer ceases to exert further influence on the cable 47, and the latter is free to be operated again by hand. The next time the cable 47 is operated by hand the rod 52 is drawn down and carries with it the cable d2, thus equalizing the branches 43 and partially rotating the sheave 57. In this way the cable 63 Lees tee is restored to normal position. The counterweights 4.4 prevent the branches :3 from becoming disengaged from the sheaves 39.

Extending below the edge of the floor 7, which is directly in front of the elevator well, is a horizontal, yielding or flexible member in the form of a chain, cable, cord, or the like, the same being represented at 64. This is the primary element of the landing guard. And extending below all four edges of the elevator platform 9 is a. similar member, in similar form, which is represented at 65. "This second flexible member is the primary element of the elevator guard. A secondary element of the landing guard consists of a plurality of vertical chains, cords, or the like, the same being represented at 66, which have their lower ends fastened to the cord 6%, and their upper ends fastened to the floor 7. And a secondary element of the elevator guard consists of a plurality of vertical chains, cords, or the like, the same being represented at 67, which have their lower ends fastened to the cord 65 in front, and their upper ends fastened to the upper parts of four, angular, depending brackets 68 that are secured to the platform 9 beneath the same. A tertiary element of the elevator guard consists of a netting of chains, cords, or the like, or an equivalent member or members, the same being represented, at 69, in the form of a netting of cords. The netting 69 is attached to the cord 65.

Each of the front corner brackets and the left-hand rear corner bracket 68 is provided with a shelf 70 in which is set a vertical stud 71 for a horizontal sheave '73, such sheave being above such shelf, and mounted on suitably-located studs 74. which project inwardly from the sides of such bracket are two vertical sheaves 75see Figs. 10 and 12. Depending from the right-hand flange of the rigl'it-hand rear bracket 68 is a hanger 76 which has at the bottom an outwardlyextending lug 77, as shown in Figs. 10, 12, and l l. The cord 65 has one end attached at 78 to a latch '79 which is pivotally connected et- 80 with the front part of the right hand front bracket 68, behind such part. The cord 65 extends, from the latch 79, around the three sheaves 73 to a sheave 81 which is mounted on a stud 82 that projects inwardly from, the right-hand front bracket 68, and said cord passes under and over said last-named sheave to and through the 111 77. A spring 83 has its front end attached to the right-hand rear bracket. 68 and its forward end attached to the end of the cord 65 which has been passed rearwardly through the lug 77. A stop block 84- is secured to the reach of the cord 65 that passes through the lug 77, in front of said lug, and said block is drawn into contact with said lug by the spring 83, thus limiting the amount of tension put upon said cord by said spring. The block 84 is so adjusted on the cord 65 as to enable the spring 83 to maintain said cord in a taut condition. The sheaves 7 5 are above the cord 65 and prevent the latter when forced upwardly from becoming disengaged from the sheaves 73. The spring 83, although adapted to yield when an excessive pressure or force is applied to the cord 65, is, nevertherless, of sufficient strength to permit said cord to operate the latch 69, in the manner hereinafter explained, at such time as the cord is deflected by lateral force or pressure thereon from any direction. The cord 65 may be deflected by force applied directly thereto, or by force applied indirectly through the medium of any of the vertical cords 67 or of the horizontal netting 69, which latter is attached at all four sides to said cord 65. The cords 67 are here present on all sides, but might be provided on any one, two, or three sides.

A bracket 85 is secured to the inside of the wall 2 adjacent to the front edge thereof, and such bracket is provided with an upper stud 86 which extends inwardly, and a lower stud 87 which extends forwardly. Sheaves 88 and 89 are mounted on the studs 86 and 87, respectively. The right-hand end of the cord 64 is attached, at 90, to a latch 91 that is pivotally connected at 92 with a bracket 93, and said cord extends to the left, from said latch, beneath the sheave 89, upwardly over the sheave 88, and downwardly to a spring 94. The spring 94 has its upper end attached to the lower end of the cord 64, and its lower end attached to a pin 95 which extends inwardly from the wall 2. The bottom of the sheave 89 is on a level with the point of attachment 90 for the cord 64., and the front of the sheave 88, the axis of which sheave is at rightangles to the axis of the sheave 89, is in line with the left-hand end of the horizontal diameter of said sheave 89. The spring 94 is of sufficient strength to retain the cord 64 normally in a taut condition, but not of sufficient strength to prevent said cord from operating the latch 91, as subsequently explained, whenever force or pressure is applied laterally to said cord from any direction. The spring 94 yields, however. under excessive pressure or force applied to the cord 64, just as in the other case. and such force or pressure may be applied either directly to said cord, or through the medium of the vertical cords 66. The bracket 93 is an angle-iron which is secured to the inner face of the wall 1 at the front edge thereof. has an inwardly projecting part, and the latch 91 is pivoted against the front side of such inwardlyprojecting part.

Trip mechanisms, presently to be described, and which include the latches 79 and 91, are interposed between the cords 65 and 64 and the safety cable 63 which operates through the starting and stopping cable 47 to cause the power to be shut ofi from the elevator. Each of these mechanisms is tripped by a slight pull on whichever of the aforesaid cords is connected therewith, as will subsequently more fully appear. Any object which extends beyond the front edge of the platform 9, when the latter is ascend.- ing to the floor 7, either encounters the cord 64 or the cords 66 and so tends to draw said cord 64 inwardly at the ends, and any object which extends into the well from the adjacent edge of said floor, when said platform is descending to said floor, is either contacted with by the cord 65 or encounters the cords 67 and so tends to cause said cord 65 to be drawn inwardly at the ends. Likewise, an obstruction below the platform 9, in the bottom of the well, is contacted with by the netting 69, when the elevator is descending, and acts on the cord 65 to draw it inwardly at the ends. Owing to the construction of the guards, of which the cords 64 and 65 are the primary elements, any strain applied thereto from any direction is effective.

Secured to the right-hand side of theright hand front bracket 68 is a block 96, Figs. 1, 4, and 10. There is a vertical passage extending through the block 96 for the reception of the front reach of the safety cable 63, and also a central opening in the backside of such block to receive the outer-end portion of a binder or clutch 97, said opening communicating with said passage.

The platform' 9 at the right-hand side and the right-hand upright 10 are provided with two pairs of lugs 98. the bottom pair being below the top of said platform and the upper pair being at the upper end of said upright. There are openings in the lugs 98. one of which is clearly shown at 99. in Fig. 11, for the passage of the rear reach of the safety cable 63. Adjacent to the outer terminals of the lugs 98 are additional openings for a vertical pivot rod 100. Necessarily the upper and lower pairs of lugs 98 are so disposed relatively as to locat each of the openings therein in the same vertical line. A vertical shoe 101, which I term a shoe. is provided at the rear or inner edge with a plurality of lugs 102. The upper and under lugs 102 are of a size and in position to be received between the lugs 98 in the two pairs, and all of said lugs 102 are perforated'to receive the pivot rod 100. Thus it is seen that the shoe 101 is supported from the elevator and capable of being swung away from the platform 9 and to the left into close proximity with said platform.

to the right- The shoe 101 extends below the horizontal plane of the bottom of the platform 9, and above the horizontal plane of the top of the upright 10 and beam 11. The upper and lower terminals of the shoe 101 are beveled or curved substantially as shown in Fig. 12, so that said shoe in ascending or descending may exert a. wedging action outwardly or to the right. Each of the top and bottom lugs 102 is provided with a hooked, gripping finger 103 which is behind the rod 92 and in position. when the shoe 101 is swung toward the elevator or inwardly. to pass by the adjacent edges of the associated openings 99, and thus grip the contiguous portion of the cable 63, such finger extending rearwardly and being curved to the right in its general aspect. A in 104 projects from the forward edge of the shoe. Means may be provided normally to retain the shoe 101 in its outward position, in order normally to prevent the fingers 103 from binding on or wearing the cable 63 as the elevator ascends and descends, and to that end a light spring 105 may be interposed between the platform 9 and said shoe, as shown in Fig. 8. It will presently be seen that this shoe is an element which cooperates or is closely associated with the trip and resetting mechanisms.

The landing-trip mechanism, illustrated in Figs. 1, 3, 15, and 16, comprises, with the latch 91. and in a sense the cords 64 and 66, a slide 106. a spring'107, and an angular rod or rocker 108. The cord 64: is attached at 90 to the latch 91 below the pivot 92, and said latch has an arrn 109 that extends to the right of said latch above the horizontal plane of said pivot. The slide 106 is a vertical member having a longitudinal slot 110 in the lower portion thereof. and said slide is attached to the front side of the bracket 93 by means of a screw 111 that passes through said slot into threaded engagement with said bracket. The screw 111 is sufliciently loose to enable the slide 106 to move up and down. The spring 107 is attached at the upper end to the slide 106 and at the lower end to the arm 109. The rod 108 is a rocking member having a horizontal part journaled in the front of the bracket 93 immediately adjacent to the wall 1, and in a bearing 112 that is secured to said wall behind said bracket. That portion of the rod or rocker 108 that is in front of the bracket 93 extends to the left and has its free terminal pivoted at 113 to the upper part of the slide 106. The rear terminal of the rocker 108 is in the form of an upwardly-directed and rearwardly-extending crank-arm 114. The crank-arm may be projected into the path of the shoe 101, or may be forcedagainst said shoe to actuate the same innaeaaas wardly; moreover, said crank-arm may itself be actuated outwardly or to the right by the shoe.

When the crank-arm 111 is actuated into its more directly vertical position and in contact with the wall 1, the rod 108 is rocked in such a manner as to raise the slide 106, against the resiliency of the spring 107, and at the same time, through the medium of said spring, to cause the arm 109 to be swung upwardly, the latch 91 then rocking on the pivot 92 to the left into supporting position beneath the elevated slide. i-lny undue strain or pressure applied either directly or indirectly to the cord 6% causes the latch 9l to be rocked on its pivot 92, against the resiliency of the spring 107, out of engagement with the slide 102, when said spring draws down said slide and rocks the rod 108 in such a manner as to carry the crank-arm 114; to the left or inwardly away from the wall 1.

The elevator-trip mechanism, illustrated in Figs. 1, 4t, 10, 12, and 1 1, comprises, with the latch 79. and in a sense the cords and 67 and the netting 69, an approximately vertical, spring-pressed plunger 115, a rock shaft 116, and an arm 117. The pivot 80 is adjacent to the lower, left-hand corner of the latch 79, and the cord 65 is connected at 78 with said latch directly above said pivot. The latch 79 is provided at the right of the pivot 80 with a rearwardly-extending, perforated lip 118 through which the lower terminal of the plunger 115 extends. Adjustably secured to the plunger 115 above the lip 118 is a collar 119, and a spring 120 is interposed between said lip and said collar. The spring 120 has a tendency constantly to elevate the plunger 115 and rocks the latch 79 inwardly at the top. At the top of the latch 79 is a head that projects a short distance to the right, and is provided with a roarwardly-extending stud 121 upon which is mounted an antidriction roll 122. The roll 122 is in position to engage the collar 119 from above, when the plunger 115 is depressed and the latch 79 is rocked outwardly at the top, against the resiliency of the spring 120, and to hold said collar and plunger in their depressed or retracted positions. The rock-shaft 116 is journaled above the latch 79 in front of the aforesaid corner bracket, extends rearwardly from said front, and is journaled at the rear terminal in a bearing 123 that depends from the under side of one of the corner bracket flanges. An arm 117 is rigidly attached to the rock-shaft 116, and extends to the right from the latter. The free terminal of the arm 117 is pivotally connected at 124, with the upper terminal of the plunger 115.

Any undue strain or pressure applied either directly or indirectly to the cord 65 mes es causes the latch 7 9 to be rocked on its pivot 80 to the left, ano thus to remove from the collar 119 the restraining influence of said latch, which influence is applied directly through the roll 122, withthe result that the spring 120 causes the plunger 115 to be elevated and the rock-shaft 116 to be partially rotated, through the medium or the arm 117, the partial rotation thus imparted to said rock-shaft being to the left. The movement thus imparted by said spring being limited by the connections between aid plunger and the lip 118 and arm 117. Upon a reverse movement imparted to the rock-shaft 116, the plunger 115 is forced downwardly, against the resiliency of the spring 120, until the roll 122 is moved into place again above the collar 119. The roll 122 is caused to take this position at this time, because the plunger 115 in moving downward compresses the spring 120 and through the latter and the lip 118 rocks the latch 79 in such a manner as to carry the roll 122 toward the plunger 115 and over the collar 119. Upon the removal of the force that depresses the plunger and com presses the spring, the collar 119 is thrust by said spring against the roll 122, and the parts are held in readiness to be tripped the next time. The connection between the plunger 115 and the lip 118 is sufficiently loose to enable the above-described operations to take place.

Extending to the right from the rockshaft 116, adjacent to the bearing 123, is a resetting arm 125, and it is through the medium of such arm that said rock-shaft is act'- uated to depress the plunger 115 and cause the latch 79 to lock said plunger in its low position, or, in other words, that this trip mechanism is reset. The arm 125 extends beyond the corresponding side or edge of the platform 9.

The inner terminal of the clutch 79 is pivotally connected at 126 with an arm 127 that depends from the rock-shaft 116. The motion imparted to the rock-shaft 116 by the plunger 115, when the latter is released to the spring 120, causes, through the medium of the arm 127 the clutch 97 to be thrust outwardly into engagement with that part of the cable 63 that is in the block 96; and the motion imparted to said rock-shaft, when said. plunger is forced downwardly to reset the same, causes through the same medium said clutch to be withdrawn from such engagement.

The resetting device. illustrated in Figs. 1, 10, 12, 13, and 14, comprises a vertical, spring-pressed plunger 128 located above the protruding terminal of the arm .125. bracket 129 is mounted on and secured to the platform 9 adjacent to the right-hand edge thereof, andthe plunger 128 is connected with said bracket and with said platform edge by means of upper and under screws 130, which screws pass through longitudinal slots 131-131 in said plunger and are respectively tapped into said bracket and platform. The screws 130 hold the plunger 128 in place without preventing the up and down movement thereof. Both the bracket 129 and the plunger 128 have inwardly-extending lips between which is a spring 132. The spring 132 is arranged and adapted to retain the plunger 128 in its most elevated position, with the bottoms of the slots 131' bearing against the screws 130. Extending outwardly from the rear edge of the plunger 128 is a cam-lug 133. lVhen the shoe 101 is swung inwardly, its pin 104 is in the path of the can'i-lug 133, which latter has a downwardlyand inwardly-inclined outer edge to contact with said pin. 5

Upon forcing the plunger 128 downward ly, against the resiliency of the spring 132. the cam-lug 183 encounters the pin 104 and swings the shoe 101 outwardly on its pivot rod 100, provided said shoe is inwardly disposed, on the one hand, and the bottom of said plunger encounters the arm 124 if elevated, and, through the medium of said arm, actuates the rock-shaft 116 in the direction to reset the plunger 115 and withdraw the clutch 97 from gripping position, on the other hand. The outward movement imparted to the shoe 101, by the downwardlymoving plunger 128, causes said shoe to release the cable 63, and to act on the cranl' arm 114 and reset the slide 106, provided said slide has been tripped.

The operation of this appliance as a whole is described as follows:

To cause the elevator to descend, the front reach of the starting and stopping cable 47 is drawn downwardly by hand, which action shifts the rearbelt 28 from the rear pulley 26 onto the pulley 27, through the medium of the belt shipper, with the result that the drum 18 is rotated in the direction to unwind the cable 15. Upon drawing down the front reach of the cable 47, the block 54 on said reach moves downwardly and carries with it the cross-head 53 and the equalizer rod 52 into the posit-ion indicated by dotted lines in Fig. 2. The descent of the rod 52 takes the slack out of the equalizer cable 42,

it being understood that normally or when said rod is in elevated position said cable 42 with its branches 43 is slack between the sheaves 40 and 39. Assuming, now, that. as the descending platform approaches the floor 7, the cord 65 is deflected, either by force applied to some one or more of the cords 67 or directly to said cord 65 itself, (or the force may be applied to said cord 65 through the medium of the netting 69 when said plat-form is approaching more nearly to the bottom of the well). said cord 65 exerts a pull on the latch 7 9 and causes said latch to release the plunger 115 to the spring 12 when said spring forces said plunger upwardly, and thereby causes the arm 117 and the rock-shaft 110 to be operated in the direction to force the clutch 97 against that portion of the safety cable 63 which at the instant is in the bloclr 96, through the medium of the arm 127. Thus the front reach of the cable 63 is gripped and carried down with the descending elevator. This move ment of the cable 63 imparts a partial forward revolution to the sheaves 60 and 57, the partial revolution of said sheave 57 is transmitted through the front cable branch 43 and the cable 4:2 to the rod 52, and the latter is drawn upwardly. The crosshead 53, in moving upwardly with the rod 52, takes with it the front bloclt 54v and thus carries upwardly the front reach of the cable 47. At the same time the rear reach of the cable 47 descends and the movement of said cable is checked when the rear block 5st and the cross-head 53 come into contact with each other. This movement of the cable 47 causes the rear belt 28 to be shifted from the pulley 27 to the rear pulley 26, when the power is disconnected from the elevator and the latter comes to a stop.

After the elevator comes to a stop, the resetting plunger 128 is forced downwardly to reset the elevator-trip mechanism. In the resetting operation the cable 63 is released from the grip of the clutch 97 and left free. The next time the cable 17 is actuated to start the elevator, the movement imparted thereby to the rod 52 is transmitted through said rod and the cable 42 to the front branch 43, the latter partially rotates the sheave 57 and the sheave 60 in the direc tion opposite to that in which they were rotated when the cable 63 was gripped by the clutch 97, and said cable 63 is thereby caused to reassume its normal or initial po sition.

The force of the spring 120, which is transmitted to the clutch 97 through the intervening parts and members, is suliicient to cause said clutch to grip the cable 03 and bring about the operations necessary to stop the elevator, but is not sufficient to prevent said clutch from slipping on said cable 63 in the event the elevator continues its descent after the power has been shut off.

and its branches 43 just as it did in the previous case. Assuming, now, that the platform 9 is approaching the floor 7, and that the cord 64% is deflected, either by force applied to some one or more of the cords 66 or directly to said cord 64 itself, the latter exerts a pull on the latch 91 and trips the same, when the spring 107 causes the slide 106 to descend and the rod 108 to be rocked to the left. The shoe 101 being of considerable length. or extending a considerable distance above the platform 0, is in the path of the crank-arm 11s when the same is thrown over to the left, and said shoe is swung in the same direction by said crankarm, with the result that the gripping fingers 103 bind between them and the sides of the openings 99 in the lugs 98 the portions of the rear reach of the cable 63 that at the instant are in said openings. The rear reach of the cable 63 is carried upwardly with the ascending elevator, and the movement of said cable is transmitted, through the sheaves 00 and 57, front cable branch 48, and cable 42, to the rod 52, and the latter with its cross-head is thereby drawn upwardly. and with said cross-head.

the rear block 54 and the rear reach of the cable 4-1-7. The movement thus imparted to the cable 47 causes the front belt 28 to be shifted from the pulley 27 to the front pulley 26, and the power to be disconnected from the elevator.

After the elevator comes to a stop, the resetting plunger 128 is forced downwardly to reset the landing-trip mechanism. The resetting at this time is effected by the forcible, outward swinging movement imparted to the shoe 101 by the cam-lug when it contacts with the pin 104-, since said shoe then forces the crank-arm 114 over against the wall 1. The movement to the right of the shoe 101 carries the fingers 103 out of gripping contact with the cable 63, and the latter is restored to initial position when the cable 47 is next operated to start the elevator.

The force of the spring 107 transmitted to the shoe 101, through the intervening; parts and members. is sufficient to cause the fingers 103 to grip the cable 68 firmly enough to shift said cable for the purpose of bringing about the operation of the cable 47 for the stopping of the elevator, but is not sufficient to prevent the gripping parts from slipping on said first-named cable in the event the elevator continues to ascend after the power has been shut ofi.

In the event the landing-trip mechanism be sprung, while the elevator is ascending or descending, and before the shoe 101 arrives at the cranlcarm 114. the elevator continues to move until either the upper or lower terminal. of said shoe, as the case may be, encounters said crank-arm, when said shoe is thereby actuated inwardly, grips the safety cable 63, and causes the elevator to be stopped. This result is produced, because, when the mechanism is tripped, the crankarm 114 is thrown over to the left, and the spring 107 is strong enough to retain said crank-arm, when contacted with by the shoe 101, in such position. One or the other of the beveled terminals of the shoe 101 first encounters the crank-arm 114 and as said shoe continues to move the latter is forced toward the platform 9 by the wedging action of such terminal. In descending, the fingers 103 of the shoe 101 are caused to grip the rear reach of the cable 63 and carry the same downwardly, thus transmitting power to actuate the cable 47 through the rear cable branch 3; and in ascending, said fingers grip said reach and carry the same upwardly, thus transmitting power to actuate the cable 47 through the front cable branch 43. In either case the cable 47 is actuated in such a manner as to bring about the disconnection of k the power from the elevator, and the stopping of the same before it arrives at the next landing or floor. The shoe is caused to release the cable 63 and the landing-trip mechanism is reset by the same means and in the same manner as previously described. This provision is highly important because of the control of the elevator afforded at the landing and while the elevator is at a distant point and approaching said landing from I either above or below.

The counterweights 44 drop and carry down the branches 43 and cable 42, and the latter draws up the rod 52, when the cable 47 is shifted by hand into neutral position, until the cross-head 53 contacts with the blocks 54, thus disposing the equalizer in readiness for the next shift imparted by hand to said cable 47. The counterweights also prevent the branches 43 from slipping off of the sheaves 39.

In the event the elevator is started and stopped by an electric controller, an electric switch, such as is shown in Fig. 6, is used to open and close the electric circuit. This switch consists of a fixed contact member 134, an oscillatory contact member 135 pivotally connected at 136 with a bracket 137, and a spring 138 arranged to force said oscillatory member into contact with said fixed member, and so to close the circuit. 'The contact member 134 and the bracket 137 are secured to the underside of the platform 9, which platform is of wood so that said member and bracket are insulated. Wires 139 and 140 are attached, respectively, to the contact member 134 and the bracket 137 with which the contact member 135 is pivatally connected. The contact member 135 is in the form of a T with the head standing vertically and at the right of the bracket 137, and a roller 141 having a periphery of insulating material is mounted against the front side of the lower arm of said head. Secured to the'rock-shaft 116, behind the bearing bracket 123, is an arm 142 which extends to the left over the roller 141. Loosely mounted on the rock-shaft 116 behind the arm 142 is an arm 143 which also extends to the left over the roll 141. The arm 142 must not, of course, contact with the switch member 135. The hub of the arm 143 extends upwardly and has pivotally connected thereto at 144 the inner terminal of a rod 145. The rod 145 extends outwardly, through an opening in the adjacent fiangeat the top of the front, right-hand corner bracket 68, into the path of the shoe 101, as shown in Figs. 6 and 10.

When the latch 79 is tripped by thecord 65, the rock-shaft 116 is partially rotated by the plunger 115, under the influence of the spring 120, in the direction to swing the arm 142 downwardly. The arm 142 when swung downwardly carries with it the roll 141 and thus rocks the contact member 133 on its pivot 136 and against the resiliency of the spring 138 away from the contact member 134, thus breaking the connection and opening the circuit so that the power is shut oft from the elevator. Upon resetting the plunger 115 the spring 138 causes the contact member 135 to return to closed position. Necessarily the spring 120 must be strong enough to overcome the resistance of the spring 138, as well as the frictional resistance of the parts moved by said first-named spring. The clutch 97 is not a factor in the electrically-controlled mechanism, but might be utilized as a stop to limit the movement of the parts when released by the spring 120;

When the latch 91 is tripped by the cord 64, and the shoe 101 is in the path of the crank-arm 114, said shoe is forced inwardly by said crank-arm, carries with it the rod 145, and thus rocks the arm 143 downward- 1y. The arm 143 in swinging downwardly carries with it the contact member 135 and opens the switch in the same manner as the latter is opened by the arm 142. As soon as the shoe 101 swings outwardly again the spring 138 acts to close the switch and restore the parts to their former positions.

If the latch 79 be tripped by the cord while the elevator is ascending or descending, but before the shoe 101 arrives at the crank-arm 114, said shoe is actuated inwardly by said crank-arm upon arriving at and contacting with the same, and causes the switch member 135 to be separated from the switch member 134, in the same manner as when said shoe is forced inwardly by the movement imparted to it by the crankarm 114.

Thus it is seen that my appliance is as well adapted as a safety stop for electrically-controlled elevators as for cablewcontrolled elevators, and this withoutmaking any radical change in said. appliance.

From the foregoing it; will be clear that, when the shoe 101 is hrthe f eld ofiaction of the crank-arm Llfl at the time .the landgrip me hanis is p ng, a crankarm in beingforced over to the left carries with it said, shoe; and that when said shoe is.either aboveor below such field whensaid mechanism is sprung, the shoe is forced inwardly :by the then stationary crank-arm. In other words, the shoe may be actuated inwardly either by the movement of the crank-arm, or by the movement of the shoe in contact with said .cranlearin while the latter is stationary but in trippedlposition.

The resetting of the trip mechanisms when employed inconnectiqn with the starting andstoppingelectric switch is accomplished in the same manner as when said mechanismsare employed in,connection with the starting andstopping cable.

It is conceivable that an elevator might be provided with both cable.- and electric-controlling means or mechanisms.
